Abstract

In a relativistic quark model we study the structure of the N(1710) resonance, and the \ensuremathγ^*N\ensuremath→N(1710) reaction focusing on the high momentum transfer region, where the valence quark degrees of freedom are expected to be dominant. The N(1710) resonance, a state with spin 1/2 and positive parity (J^P=(1)/(2)⁺), can possibly be interpreted as the second radial excitation of the nucleon, after the Roper, N(1440). We calculate the \ensuremathγ^*N\ensuremath→N(1710) helicity amplitudes, and predict that they are almost identical to those of the \ensuremathγ^*N\ensuremath→N(1440) reaction in the high momentum transfer region. Thus, future measurement of the helicity amplitudes for the \ensuremathγ^*N\ensuremath→N(1710) reaction can give a significant hint on the internal structure of the N(1710) state.
